What should my bromine or chlorine reading be?

Industry standards for chlorine in pools is 1.0 to 3.0 ppm. For spas, bromine should be 2.0 to 4.0 ppm and chlorine 3.0 to 5.0 ppm. When using FROG minerals, chlorine use is reduced to 0.5 ppm for pools and chlorine or bromine can be reduced to 1.0 ppm in spas.
